OK, so here's my two cents. Over the last 15 years, porn became free. Xvideos, pornhub, youporn are free. Then, about five years ago, content providers, independent of the studios and producers, started selling their own movies and clips. Manyvids, AEBN, HotMovies, Clips4sale, OnlyFans, have started to turn the tide a bit. (I wrote about the OnlyFans dispute as well) https://kentanderson-17716.medium.com/onlyfans-and-others-attempt-to-go-straight-18ae617d50d4

Also, the term "Porn actresses," is a bit misleading. The last 'porn actress,' in my view, was Jennifer Stewart, the long forgotten "Vivid Girl." (Probably because she wasn't underage or kill herself) She did porn in the early 90s and then made a few mainstream roles and then got out of the industry altogether. She is 53 now.
